Cerebral coenurosis is a disease of small ruminants which causes economic loss worldwide. Different studies in Tanzania have reported the cause, transmission, signs, prevalence, risk factors and control measures of cerebral coenurosis. Transfer of this research-based information to livestock keepers may influence practicability and efficacy of intervention. The present study aimed at assessing the knowledge levels and control practices of coenurosis by pastoralists in Iringa district. A total of 267 respondents were interviewed on livestock management practices, knowledge, losses and coping strategies of coenurosis. The average knowledge score on coenurosis detection (definition, hosts, signs, and diagnosis, including postmortem) was 90.3%. In contrast, knowledge on infection cycle and control was zero, implying that respondents were completely not informed about etiology, transmission and control of coenurosis. Involvement of dogs in coenurosis cycle was not known to respondents such that they all gave head of sheep and goats to dogs while 82.8% had never dewormed their dogs. About 83% of respondents experienced at least, one cases of coenurosis in the last 12 months. There was no formal coenurosis control program, but heating the head of sick animal with hot iron, selling, slaughter, treatment with antibiotics, or local herbs and doing nothing were the reported management strategies. Lack of knowledge on the cause, transmission and control of cerebral coenurosis may be associated with inappropriate animal management and control of coenurosis in pastoral community in Iringa rural District, including transmission facilitating practices. A coenurosis training package is recommended to farmers before intervention program is instituted.

Resistance against synthetic antimicrobial agents is one of the major global public health challenges that compel scientists to search for alternatives including those of plants origin. Staphylococcus aureus and Escherichia coli are bacteria responsible for a variety of infections and diseases that causes significant morbidity and mortality in humans and animals. E. coli is widely distributed in nature and commonly found in lower gastro intestinal tracts of most warm-blooded animals associated with urinary tract infections and enterocolitis in humans and colibacillosis in poultry. This study was carried out to investigate antimicrobial activity of methanolic leaf extracts of Bidens pilosa against S. aureus and E. coli. Agar well diffusion method was used to assess antimicrobial activity of the leaf extracts at 20%, 50% and 70% concentrations respectively based on measured zone of inhibition. The leaf extracts of Bidens pilosa produced significant zone of inhibition indicating its antimicrobial activity against E. coli and S. aureus. The antimicrobial activity was demonstrated in all concentrations however, the highest zone of inhibition (18.5mm and 32mm) for E. coli and S. aureus respectively was at 70% concentration. The results shows that Bidens pilosa leaf extracts have antimicrobial activity against the tested bacteria and have the potential for further development including identification of active components that can be tested for treatment of E. coli and S. aureus associated conditions.

Understanding of the larval trematode infections in snail intermediate hosts is essential in designing appropriate control measures. The current study was designed to determine larval trematode infection and seasonal variations in freshwater intermediate host snails Iringa and Arumeru Districts where trematode infections in cattle are endemic. A repeated cross-sectional study was adopted whereby Snails were collected three times a year (dry, early wet and mid wet). The selection of water bodies for sampling was based on random sampling and snails were collected by scooping method. The collected snails were identified based on the published morphological keys. A total of 2,016 snails were collected and 134 (6.6%) were found to be infected with trematode larvae. Six species of snails were identified that were Radix natalensis, Bulinus africanus group snails, Bulinus tropicus group snails, Bulinus forskalli group snails, Biomphalaria pfeifferi and Ceratophallous natalensis. Five morphologically different types of cercariae were identified that included gymnocephalous, amphistomes, mammalian Schistosoma, avian Schistosoma and Xiphidiocercariae. The findings on overall seasonal snail infection rates indicated low rate during the wet season while peak of infections were in the dry and early wet seasons. It is concluded that domesticated ruminants in the study areas are at high risk of getting infected with the trematodes (Fasciola and amphistomes) during dry and early wet seasons. Therefore, deworming of domesticated ruminants with an effective flukicide is recommended at the end of the wet season and followed by a treatment in mid dry season and the last treatment in early wet season.

Antimicrobial resistance is a serious and escalating threat to global health. This study established a baseline antimicrobial resistance profile and prevalence for cloacal Escherichia coli in chickens in central Tanzania. Animal husbandry practices, flock size, and chicken breed were recorded for risk factor evaluation to elucidate potential drivers of resistance across populations. Cloacal samples were collected from poultry in Iringa, Tanzania, and E. coli isolates cultured were then tested for susceptibility to seven medically important antimicrobial drugs: ampicillin, amoxicillin-clavulanate, cefoxitin, enrofloxacin, gentamicin, sulfamethoxazole-trimethoprim, and tetracycline using the Kirby-Bauer disk diffusion method. Over 94% of the 59 E. coli isolates tested were resistant to at least one antimicrobial drug, and over 61% of isolates were resistant to three or more classes of antimicrobial drugs. The highest prevalence of resistance found was to tetracycline and sulfamethoxazole-trimethoprim (88% and 86%, respectively), which were used regularly on many sampled chickens. Previous antimicrobial usage emerged as the only significant risk factor associated with increased detection of multi-drug resistant E. coli. Further surveillance and educational outreach about antimicrobial resistance and stewardship is recommended to reduce antimicrobial drug use and to limit the potential spread of resistance to antimicrobial drugs in Tanzania.

The presence of Salmonella in food products and emergence of antibiotic resistance are the major challenges facing public health policies. A total of 2749 crocodile meat samples obtained from the Central Veterinary Laboratories in Zimbabwe were screened for Salmonella specieswere collected from three Zimbabwean commercial farms between the year 2012 and 2019 for a retrospective observational study to determine the prevalence and magnitude of antibiotics resistant Salmonella species in crocodile meat. The isolation of Salmonella was in accordance with the ISO 6579:2002 and the antibiotic susceptibility testing was carried out based on Clinical and Laboratory Standard Institute’s recommendations by means of the Kirby-Bauer disk diffusion method. SILAB Database was used to determine the prevalence of Salmonella species. Prevalence was stratified by year and farms. Twenty Salmonella isolates were identified using biochemical tests, and 15 were confirmed by polymerase chain reaction (PCR). Antimicrobial susceptibility profiles of the confirmed Salmonella isolates were examined using 14 antibiotics. The overall prevalence of Salmonella species in crocodile meat samples was 0.5%. The prevalence of Salmonella species ranged from 0.04% to 0.44% in the crocodile meat samples and annual prevalence ranged from 0.01% to 1%. The highest prevalence of Salmonella (4.4%) was recorded in the year 2012. Salmonella isolates from one of the three tested farms were resistant to Erythromycin (73.33%), Ampicillin (80%), and Penicillin G (100%). Generally, Salmonella isolates displayed lower resistance to Cefepime, Ceftriaxone, Amikacin, Tetracycline, Ertapenem, Florfenicol, and Erythromycin (0-53.33%) whereas all Salmonella isolates showed susceptibility to Cefepime, Ceftriaxone, Ertapenem, and Florfenicol. Although the study indicates low prevalence of Salmonella species in crocodile meat, there is a need for strict implementation of Hazard Analysis Critical Control Point (HACCP) to reduce contamination rates in meat and its products

An eight-month-old, 2.7 kg, male, neutered mixed breed cat was presented at the Sokoine University of Agriculture Teaching Animal Hospital with a history of lameness involving hind limbs, lethargy, anorexia and failure to urinate or defecate. Abdominal palpation revealed a distended urinary bladder and firm faeces within the colon. Manipulation of the hips elicited pain and lower lumbar pain was also elicited on palpation. Radiographic examination revealed, an old fracture of the sacrum, lordosis of the lumbar spine with indented vertebral end plates, left sacroiliac joint subluxation and abnormally ventral angling of the ilial wings. Narrowing of the pelvic canal was also observed. A diagnosis of old fractures of the sacrum, left sacral iliac subluxation and narrowing of the pelvic canal was made based on the history, clinical and radiographic examination. Limitation of activity for three weeks was recommended to facilitate healing process. The owner reported the patient had a gradual recovery from lameness.

Mastitis is a global challenge for the dairy industry and mastitogenic bacteria play a critical role among other causes. Many mastitogenic bacteria are becoming resistant to single or combination antibiotic therapy, making mastitis cases difficult to cure. Nevertheless, there is insufficient evidence on the occurrence and antibiotic resistance patterns of mastitogenic bacteria in commercial dairy and communal farms in the Midland Province of Zimbabwe that might support a holistic approach to mastitis mitigation. A cross-sectional study aimed to isolate and evaluate the antibiotic susceptibility patterns of mastitogenic bacteria from cattle with clinical mastitis was conducted. A total of 164 milk samples were analyzed, of which 36.6% (60) samples were collected from commercial farmers, and 63.4% (104) came from communal farmers. The samples were cultured on standard media and sensitivity patterns of the identified bacteria were tested against 14 antibiotics using the Kirby-Bauer disc diffusion method. All milk samples from communal farms were positive for mastitogenic bacteria compared to 88% (53) of mastitogenic positive milk samples from commercial farms. The most common microorganisms from all the 157-mastitogenic positive milk samples were Staphylococcus aureus (37.5%) and Escherichia coli (23.3%). The highest resistance was observed against Penicillin, Erythromycin, Ampicillin, and Lincomycin, whereas most isolates were susceptible to Sulphamethoxazole, gentamycin, neomycin, kanamycin, cloxacillin, ertapenem, ceftriaxone, Amp-Ampicillin, amikacin, vancomycin, and tetracycline. Futher research to investigate the significance of resistant mastogenic bacteria in terms of Veterinary costs, production losses and potential public health transmission of antibiotic resistant mastogenic bacteria is recommended

Avian leukosis is caused by various avian retroviruses which induce a variety of benign and malignant neoplasm in chickens with subsequent economic losses to the poultry industry. A survey of avian leukosis in hatchable eggs of apparently healthy chickens was carried out in an attempt to determine the prevalence of avian leukosis virus (ALV) in exotic breeders and free-range indigenous chickens in Oyo state. A total of 188 (76 exotic breeders and 112 free-range chickens) albumen of hatchable eggs were obtained from 3 different commercial breeder farms and 12 free-range indigenous chicken farms. Eggs were tested by an antigen capture enzyme-linked immunosorbent assay (ELISA) technique. Eleven out of the 76 albumen obtained from eggs of exotic breeders tested positive to ALV antigen which represents 14.5% while 37 of the 112 albumen from free-range indigenous eggs were confirmed as positive representing 33%. Overall prevalence rate of 25% was recorded for all eggs sampled with the highest prevalence of ALV antigen detected in free-range indigenous chickens than the exotic chickens. The results emphasizes the control of the Avian Leukosis transmission by including both exotic and free-range indigenous birds as wells as the use of ALV free eggs in hatcheries

Socio-cultural settings and lifestyles of communities in Taenia solium taeniosis/cysticercosis (TSTC) in endemic areas influence significantly the epidemiology of the disease. This study investigated the community perceptions and practices influencing the occurrence and endemicity of TSTC. A cross-sectional survey focusing on pig-keeping households was carried out in three wards of Iringa District Council as a representative of other TSTC endemic areas. Questionnaire and observation checklists were employed for data collection. Eighty-seven (99%) of the 88 surveyed households had pit latrines, and 84(95%) of the households were found using their latrines. These latrines varied from good to a very good quality according to subjective qualitative scores. About 294 (85%) pigs were enclosed and 52(15%) were free roaming. The results indicated poor adherence to routine pig inspection at sales (50% inspection) and less pork inspection at slaughter (50% uninspected). Furthermore, there were no authorized centres for slaughter and sales. Health Officers and farmers were comfortable with the boiling form and home prepared pork (>90%). Health Officers perceived deep-frying and roasting of pork as inappropriate preparation methods.

This study investigated the community perceptions and practices influencing the occurrence and endemicity of TSTC. A cross-sectional survey focusing on pig-keeping households was carried out in three wards of Iringa District Council as a representative of other TSTC endemic areas. Questionnaire and observation checklists were employed for data collection. Eighty-seven (99%) of the 88 surveyed households had pit latrines, and 84(95%) of the households were found using their latrines. These latrines varied from good to a very good quality according to subjective qualitative scores. About 294 (85%) pigs were enclosed and 52(15%) were free roaming. The results indicated poor adherence to routine pig inspection at sales (50% inspection) and less pork inspection at slaughter (50% uninspected). Furthermore, there were no authorized centres for slaughter and sales. Health Officers and farmers were comfortable with the boiling form and home prepared pork (>90%). Health Officers perceived deep-frying and roasting of pork as inappropriate preparation methods.

Urban vegetable farming is popular in Tanzania and other countries partly due to readily available market and reliable transport to reach consumers. River banks are usually used to grow such vegetables due to closer proximity to water and whenever necessary use such water for irrigation. However in urban settings river water pollution by toxic heavy metals and subsequent accumulation of the metals in nearby grown vegetables has been reported as among major sources of exposure to humans and animals. Heavy metals, including lead (Pb) have many health effects to human and animals ranging from acute to chronic illnesses. This study was conducted to assess the occurrence of lead in Morogoro river and in edible vegetables (Amaranthus retroflexus) grown along the river bank. Water and vegetable samples collected during dry and rainy seasons were prepared and analysed for occurrence and levels of lead using Atomic Absorption Spectrometry (AAS). It was found that concentration of Lead in the water and vegetable samples were up to 0.95 mg/L, and 0.026 mg/Kg respectively. It was also found that 77% of the water samples and 28% of the vegetable samples had lead levels above the WHO recommendations. The frequency and levels of lead occurrence varied with topographical, diurnal and seasonal characteristics of sample collection. The results of this study raise concerns on the use of water for human and animal consumption from rivers which run across urban areas and call for further studies to investigate for any health consequences to consumers
